Tonight's doodle.  Started in very messy, scribbly grayscale, overlaid with colors, then went from there.  Used quite a bit of airbrush everywhere after the initial step.  I think the light/dark contrasts worked out ok.  Not happy with the colors - I never seem to get good results from overlaying colors on top of grayscale unless I almost completely paint over the whole thing again.
